Abstract: CANADA     ABSTRACT OF THE DISCLOSURE      The invention provides a dynamic system for heat-sealing an all-plastic material in a continuous process at high speed.  The invention includes an all-plastic heat-sealable container material comprising a multiple-layer composite, in sheet form, including a core layer and at least one outer layer on one side thereof.  The layers preferably comprise thermoplastic material, the core layer material having a higher softening point than the outer layer material.  The composite sheet is conveyed through a converting, side-seaming or other apparatus at high speed, the system being tuned to dynamically heat the outer layers to a molten state for heat sealing, while the core does not soften but remains undistorted. The core is thus thermally insensitive to heat at speeds used in side-seaming the composite, and as such it supports and maintains the structure of the sealing outer layers on its exterior while they are in a molten condition.

Abstract: ABSTRACT OF THE DISCLOSURE       Ligno-cellulose material such as aspen poplar wood, is rendered suitable for use as ruminant fodder by treating the material with saturated steam at elevated pressure in a digester.  In order to enhance the yield of digestible product formed, whilst at the same time retaining economically favor-able process conditions, special process features are employed in feeding and discharging the material to and from the diges-ter, to avoid overheating the material, even locally.  The material is maintained at or above the fibre moisture satura-tion point and is compacted, prior to entry into the digester.          Then it is abruptly subjected to steam pressures and tempera-tures in the digester, so that it promptly decompresses and permits prompt and even steam penetration.  For discharging, the treated material is mechanically compacted, its free moisture content maintained at or adjusted to at least the fibre saturation point, and then discharged in small batches with substantially instantaneous decompression and cooling.

Abstract: ABSTRACT OF THE DISCLOSURE          A switch device for a printed circuit board and the resulting circuit structure including a mounting stud with a pilot threaded section and a working threaded section axially separated by an unthreaded shank and means for mounting the stud to a printed circuit board; and a hollow shell having a locknut mounted on its interior.  The distance between the two threaded sections is greater than the interior threaded axial length of the locknut to captivate the shell on the stud.  The mounting stud is permanently secured to the circuit board in a hole formed in the board passing adjacent and electrically connected to a conductor on one surface of the board and close to but spaced from a conductor on the opposite surface of the board.  The assembled shell with locknut is screwed onto the pilot end of the stud, the threaded portion of the nut passing the pilot threaded section and freely is moved to the working threaded section where continuing rotation causes the locknut thread to engage and be worked down to the board  surface.  Screwing it tightly against the surface causes electrical contact to be established between the conductors on opposite surfaces of the board through the enlarged axial end of the shell, stud and soldered connection.          If the contact is not desired, it is unscrewed a couple of turns to lift its axial end off the conductor spaced from the stud.

Abstract: The present invention relates to an improvement in the manufacture of grain-oriented silicon steels.        United States Patent No. 4,102,713 which issued to the applicant on July 25, 1978 teaches a process wherein manganese di-oxide is incorporated within a boron-bearing base coating for appli-cation to a boron-bearing steel. Oxygen in the manganese dioxide contributes to the formation of a high quality base coating on boron-bearing steels which receive a low dew point final normalize.        As a certain amount of oxygen must be present in the scale of silicon steel to render the surface susceptible to formation of a high quality base coating; a means of adding oxygen to the scale of boron-bearing steels was sought out.          The scale of boron bearing silicon steels is low in oxygen, as these steels receive a low dew point final normalize.  One such means of adding oxygen is disclosed in U.S. Patent 4,102,713.          Disclosed therein is a base coating containing manganese
